Stratmosphere sells a sunshade that works very well, except for the velcro being backwards! :(

The Audi Car cover works very well and can be purchased for $199, this is about $25 off from a dealer. I have one of these and am very happy with it, except for some powder from the inside remaining on the car after removing the cover :( The other company that people talk about for a cover is the California Car Cover company, or something to that effect. Everyone that has gotten one from them is very happy as well. They also make one for the TTR.

Hope that helps.
